Abstract

Abstract:

To investigate the effects of different thicknesses of biodegradable mulch film on soil temperature, moisture, and yield of summer-sown sweet potato, a single-factor randomized block design was adopted for comparative experiments. The results showed that 40 days after transplanting, mulch coverage increased surface soil temperature, while at 70 and 100 days after transplanting, the mulching treatments exhibited lower temperatures compared with the control. At 40 days after transplanting, soil moisture at 0 and 5 cm depths was higher in mulching treatments than in the control. The number of stem nodes and branches in mulching treatments was significantly higher than the control 40 days after transplanting. At 130 days after transplanting, the dry matter weight of mulching treatments was significantly higher than the control, with no significant differences among the biodegradable mulch treatments. The yield and marketable tuber rate of the three biodegradable mulching treatments were all significantly higher than those of the control, with biodegradable mulch exhibiting better degradation performance. This study provides a theoretical basis for the application of biodegradable mulching summer-sown sweet potato cultivation.

Key words: sweet potato, biodegradable mulch film, soil temperature and moisture, yield
